CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. 528,519, dated October30, 1894. Application filed April 9,1894: Serial No. 506,938. (Nomodel.)

To 00% whom it may concern:

Be it known that I, CHARLES S. Roenns, a citizen of the United States ofAmerica, and a resident of Atlanta, in the county of Fulton and StateofGeorgia, have made a certain new and useful Improvement inOhurn-Dashers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in'the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersand figures of reference marked thereon, which form a part of thisspecification.

The invention is illustrated in the accompanying drawings, in which-Figure l is an inverted plan view of the de-' vice forming the dasher,showing the arrangement of the dasher-blades and their form. Fig. 2 is aside elevation of the lower end of the dasher inverted. Fig. 3 is alongitudinal section of the upper end of the handle. Fig. 4 is a planthereof. Fig. 5 is a side elevation of the metallic cap. Fig. 6 is aview of the under side of a dasher-blade, showing the concavity therein..Fig. 7 is an end view of said dasher-blades showing the'cross-sectionalform thereof, at and near their inner ends. Fig.8 is a sectionon theline88, Fig. 6, showing further the concavity in the under side of theblade.

In the figures like reference marks are uniformly employed in thedesignation of corresponding elements of construction in all the views.

A is the statf which is preferably enlarged at its lower endsubstantially as shown in Fig. 2, and B are blades set therein byinserting and securing their ends in suitable grooves in the peripherythereof. The dasher blades are provided on their under sides withconcavities 1) extending over as much of .the under surface aspracticable, their upper edge being chamfered as shown at b andtheirlower or back edge being also chamfered or rounded as shown at b Fig. 8.These blades are set angularly to their line of motion in being passeddownwardly and upwardly in the cream, which produces a vortex in theirdescent, and as the dasher ascends through the revolving mass of creamand milk, the same is by a construction hereinafter described allowed torevolve with said milk and cream and so does not break the vortex orinterfere with its revolution. This is facilitated by the thin ning downor chamfering of the edges of the dasher-blades. The dish-shapedconcavities in the under side of the dasher-blades carry down air intothe cream on the descent of the dasher and said air is slowly worked outas same descends and returns upwardly through the milk, thoroughlyaerating same during the process of churning. The passing out of the airfrom the concavities is of course facilitated by the inclination of theblades and the consequent rush of milk across their un der sides in theprocess. 7

A sleeve 1 is secured to the upper end of the handle or stafi A by meansof a long screw 2 which is provided with a head and is screwed into theupper end of the staff and lies concentric and parallel thereto. Thisscrew projects from the end of the staff slightly more than the lengthof the sleeve 1, this difference being slightly more than the thicknessof the head of the bolt 2. The sleeve 1 is so shaped as to afford easygrasp for the hand. A cap 3 is secured to the tenon 4 on the upper endof the sleeve 1 and has the upper end of its concavity squared toreceive the head 5 of the bolt or screw 2 when the handle is depressedwhereby engagement is made at that time between the said bolt audconsequently the staff A and the sleeve 1. This taking place on thedepression of the dasher by application of the hand to the sleeve 1prevents the revolution of the dasher as it descends, and as theengagement is disrupted upon the upward pulling of the sleevethe dasheris allowed to move free with the circular motion of thevortex. This capalso serves to guard the head of the screw from pinching the hand of theoperator when the sleeve is drawn upwardly. The cap 3 is secured to thetenon t by means of screws 6 entering said tenon through slots 7 in thecap, which for purposes of molding in casting the said cap are made openat their lower ends, the flange 8 preventing any withdrawal of the capfrom the screws.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is
